Can someone explain permitting and drilling for stacked pays? Example: Texas RRC approves permits for twin v-shaped long laterals from one well pad, API 389-37589 (5H) and 37581 (6H). Lateral wellbores are 10,176’ long. Assuming initial drill into Wolfcamp A is profitable, operator may drill additional lateral lines into multiple vertical landing zones, i.e., Wolfcamp B, C, D.
(Q) Assume no more permits needed to drill the deeper vertical strata levels? Single RRC permit allows multiple landing zones?
(Q) How can mineral owner know if/when operator drills additional strata, if no new permit is required?
(Q) Is API 389-37581 (6H) commonly considered one well with four horizontal wellbores (strata A, B, C, D), or is it called four wells since wellbores penetrate four vertical strata?
(Q) If operators estimate well cost at $7 or $8 million, do they refer to each 10,000’ lateral line, e.g., 389-37581 might cost $30 million if four different Wolfcamp strata were drilled. Or, do they mean $7-$8 million will fund multiple horizontal wellbores from one pad/one permit?
